Copyright © 2011 American College of Sports Medicine What is Clinical Exercise Physiology? Uses physical activity and exercise to prevent or delay the onset of chronic disease in healthy individuals Provides therapeutic or functional benefits to individuals with disease conditions or physical disabilities Requires an understanding of how the body responds to acute and chronic physical activity and exercise in both a healthy and diseased condition
Copyright © 2011 American College of Sports Medicine Development of Clinical Exercise Physiology First use of physical activity and exercise in disease recovery can be traced to the 18 th and 19 th centuries Morris and colleagues studied coronary heart disease in London bus drivers and conductors –Demonstrated the relationship between physical activity and the risk of developing heart disease –Initiated interest in disease risk reduction and public health epidemiology
Copyright © 2011 American College of Sports Medicine Development of Clinical Exercise Physiology Cardiac rehabilitation programs first developed in the 1950s AHA and ACSM developed testing and training procedures for healthy and diseased individuals Late 1950s pulmonary rehabilitation programs began to use exercise
